Structure and transport properties of melt processed Ba(1-x)K(x)BiO3.

摘要

Single-phase samples of Ba(sub 1-x)K(sub x)BiO(sub 3)(00.35 with (Tc) gradually decreasing as x increases. At 10K, with decreasing potassium content, the symmetry reduces to tetragonal at x=0.35, orthorhombic at x=0.2 and finally to monoclinic at x=0.1. Normal state resistivity displays metallic behavior for 0.40
